Description:

A3967 Stepper Motor Driver Board EasyDriver Stepper Motor Driver V44 MS1 and MS2 are the logic input stepping motor subdivision resolution selectionmouth; Dir is the running direction of the motor selection mouth; Reset is used to reset chip initial value, shield all external output; Step is the pulse input port; Out1a, out1b, out2a, out2b two on the output port of the H bridge; Enable enable end; Sleep sleep mode; Sense1, sense2 as a current detection resistor h bridge; Ref is reference voltage; GND logic and power supply; RC1, RC2 to H bridge fixed deadline analog input. A3967SLB is USA production company Allegro PWM constant current control micro step driving two-phase stepper motor drive for. Working voltage up to 30V,the drive current up to 750ma, a A3967SLB can drive a two-phase stepper motor, can achieve 8 subdivided driving. PWM current control circuit chip can be through the voltage across PFD set to slow, fast, of three mixed current decay mode, if the PFD terminal voltage is higher than 0. 6vdd, then select the slow decay. If less than 0. 21vdd, then choose fast decay mode. Between the two mixed decay mode. In addition, A3967SLB can provide perfect protection, including inhibition of transient voltage, overheat protection, under voltage, prevent the current through the self-locking function. Between A3967SLB and microprocessor does not need additional interfcircuits of other, the chip by easy stepper Interface, the 8 control lines are reduced 2 (step and direction), simply input control step pulse motor, its embedded converter can achieve the control of stepper motor. A3967SLB also requires some resistance, capacitor to adjust its working parameters, the driving circuit is very simple.
